The toilet is one of the places we frequently visit in the house, at least once daily. It is the only place eager to receive us when we have had food and need to have bowel movements.

As a result, we all know it can get pretty dirty. But do you know the dirtiest places in the toilet? Let’s take a look.

1. Toilet bowl:

The toilet bowl is the part below the toilet seat we flush with water. It is the gigantic bowl-shaped part of the toilet. For obvious reasons, this is the part of the toilet where bacteria and germs thrive the most.

This part of the toilet is not just the conspicuous spots around the rim and waterline, it is also the area under the rim where water flows into the toilet bowl. This is a prime spot for mould and bacteria to grow. On average, a toilet bowl contains 3.2 million bacteria per square inch*, including germs in toilet water.

According to a research document available on the National Centre for Biotechnology Information website, numerous bacteria and viruses, when seeded into household toilets, were shown to remain in the bowl after flushing, and even continual flushing could not remove a persistent fraction.

This, according to them, results from the adsorption of the organisms to the porcelain surfaces of the bowl, with gradual elution occurring after each flush.

2. Toilet seat:

The toilet seat is another spot that can harbour bacteria and germs. Studies have shown that the toilet seat can contain up to 50 bacteria per square inch, making it one of the dirtiest places in the toilet.

Although many people consider toilet seats the public enemy №1 — the playground for organisms responsible for STDs like chlamydia or gonorrhoea, it is not a typical vehicle for transmitting infections to humans.

Many disease-causing organisms can survive for only a short time on the surface of the seat, and for an infection to occur, the germs would have to go from the toilet seat to your urethral or genital tract or through a cut or sore on the buttocks or thighs, which is possible but very unlikely.

3. Flush handle:

The flush handle is one of the most touched areas in the toilet, yet it is often left unattended during cleaning. According to some microbial habitat Studies, the flush handle can contain up to 83 bacteria per square inch.

This part of the toilet has the most contact per visit, with human hands that have come in contact with germs in or outside the toilet area.

Everyone flushes after use, and they often do so before washing their hands. Germs and bacteria can be easily transferred from one person to the other, especially in a public toilet.

4. Toilet paper holder:

Like the flush handle, the toilet paper holder is another spot that can contain bacteria and germs, especially if it is not scrubbed regularly. The holder can contain up to 50 bacteria per square inch.

Many times during cleaning, this holder is also often left out.

Many people direct their precautionary tactics to the toilet bowl and seats when these holders can deliver similar microbial species to their hands.

5. Floor:

Everything in the toilet ends on the floor, especially the flushing water. The floor around the toilet bowl and body is a breeding ground for bacteria and germs. This is true if there are any spills or splatters.

According to research, droplets produced by flushing toilets harbour both bacteria and viruses which had been seeded. The detection of bacteria and viruses falling out onto multiple surfaces in the bathroom after flushing indicated that they remain airborne long enough to settle on surfaces throughout the bathroom.

The toilet Air

The toilet air contains hundreds of bacteria, especially during flushing. The microparticles are lifted during flushing and remain airborne for a period. They settle on the toilet or other surfaces, including mirrors, curtains, brushes, creams, clothes, towels, etc.

So, what can you do to keep these areas clean? First and foremost, make sure to clean your toilet regularly with a disinfectant cleaner.

Focus on the areas, and clean the toilet brush as well. Additionally, wash your hands thoroughly after using the toilet, and consider using a paper towel to open the door when leaving the bathroom.

In conclusion, the toilet can be a dirty place. However, with some regular cleaning and good hygiene practices, you can keep it under control. Pay attention to the dirtiest places in the toilet and take steps to keep them clean. You can reduce your risk of exposure to harmful bacteria and germs.
